Thank you for the information.
I'll try to see if I can fix it.
I'm not quite sure what to do either, check out the original Godot version!

I'm looking forward to playing your game!
I think it is possible.In the project sample scene, I use this shaders at the 2d images.

It's Unity version!
This is an awesome tool!
I created Unity version (porting from your Godot ver)and works completely.
Can I publish It( github )?
